Freedoom: Phase 2 is a Doom2 styled first person shooter game using the
Doom engine. Freedoom: Phase 2 has 32 levels in one long chapter,
featuring extra monsters and a double-barrelled shotgun.
There is a massive back catalog, spanning over two decades, containing
thousands of Doom levels and other modifications (â€śmodsâ€ť) made by fans
of the original Doom game. Freedoom aims to be compatible with these and
allows most to be played without the original Doom datafiles.
Freedoom: Phase 2 aims for compatibility with Doom II and Final Doom.
